BACKGROUND

An electric balancing scooter is also known as a somatosensory scooter,Segway, etc. It is a popular transportation vehicle among modern peopleand can meet people's requirements for leisure, entertainment, andenvironmental friendliness. On the basis of the principle of “dynamicstability”, the electric balancing vehicle determines the vehicle'sposition and condition by using a gyroscope and an acceleration sensor,and calculates appropriate instructions through a sophisticated,high-speed central microprocessor, and then drives motor to makeadjustments correspondingly, so as to keep balance of the system.

The forms of existing balancing vehicles are diverse and various.

A balancing vehicle equipped with a steering rod is available in themarket. The user controls the moving direction of the balancing vehicleby adjusting the steering rod. The operation is complicated anddifficulties may occur while adjusting the steering rod. Furthermore,since the user needs to hold the steering rod and cannot make a movementlike stretching etc. at will, the fun of playing is reduced.

The Chinese Patent Application No. 201520567850.X discloses adouble-wheeled balancing vehicle, which does not need the steering rodto adjust the vehicle's motion status. However, the left and rightpedals of this two-wheeled balancing vehicle are connected by anintermediate shaft. While in use, the whole weight of a human body isborn by the intermediate shaft. The twisting of the body of thebalancing vehicle may easily cause damage, even crack, to theintermediate shaft. The balancing vehicle with this structure is proneto failure and has low stability. The reliability and security of thisbalancing vehicle also needs to be improved. Additionally, the design ofthe balancing vehicle with the intermediate shaft has a low flexibilityand a large reaction error.

The working, principle of the electric balancing vehicle provided by thepresent invention is as follows:

During the operation of the electric balancing vehicle, when the user'sleft foot steps on left pedal 10, the first touch sensing is turned on.When the user's right foot steps on right pedal 20, the second touchsensing switch is turned on. While the user's left foot steps on leftpedal 10, making left pedal 10 incline forwards or backwards, the firstsensing system which is connected in parallel to the bottom of leftpedal 10 inclines forwards or backwards along with left pedal 10. Thistime, the first sensing element detects the motion status of left pedal10 constantly, and transmits the signal to the signal processor. Thesignal processor feeds back the signal to the first motor. The motionstatus of the left wheel is adjusted according to the power output ofthe first motor. On the other hand, while the user's right foot steps onright pedal 20, making right pedal 20 incline forwards or backwards, thesecond sensing system which is connected in parallel to the bottom ofright pedal 20 inclines forwards or backwards along with right pedal 20.At this time, the second sensing element on the second sensing systemdetects the motion status of right pedal 20, and transmits the signal tothe signal processor. The second signal processor feeds back the signalto the second motor. The motion status of the right wheel is adjustedaccording to the power output of the second motor. When the user stepshard on left pedal 10 and right pedal 20 to the forward simultaneously,the left wheel and the right wheel keep rolling forwards, and thebalancing vehicle moves forwards. When the user steps hard on left pedal10 and right pedal 20 to the backward simultaneously, the left wheel andthe right wheel keep rolling backwards, and the balancing vehicle movesbackwards. However, when the stepping motion of the user makes motionstatus of left pedal 10 and that of right pedal 20 inconsistent, thebalancing vehicle will turn.

Meanwhile, the first sensing element and the second sensing element willfeed back the swing magnitude of the user's body, such that the firstmotor and the second motor could obtain different power outputs, so asto adjust the velocity of the balancing vehicle.
